Overview

CVE-2026-68237 is a known-severity vulnerability. It was published on August 10, 2026.

Technical description

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu/userq: fix indefinite fence wait during GPU reset

pre_reset only force-completes fences of MAPPED queues. A queue in any

other state (e.g. mid-eviction) keeps its last_fence pending; after a

GPU reset that fence never signals, so the eviction/suspend worker and

process teardown (amdgpu_evf_mgr_flush_suspend) wait on it forever and

wedge the machine:

INFO: task kworker/6:28 blocked for more than 120 seconds.

Workqueue: events amdgpu_eviction_fence_suspend_worker [amdgpu]

Call Trace:

dma_fence_wait_timeout+0x7e/0x130

amdgpu_userq_evict+0x67/0x140 [amdgpu]

amdgpu_eviction_fence_suspend_worker+0xd8/0x160 [amdgpu]

process_scheduled_works+0xa6/0x420

Force-complete every queue's fence regardless of state. The unmap and

mark-hung step stays gated on MAPPED, since unmapping a queue that is

not mapped is invalid.

How can CyberStrike help with CVE-2026-68237?

CyberStrike is an open-source, AI-augmented pentesting engine. Rather than flag a version number, it tests whether an issue like CVE-2026-68237 is actually reachable in your own applications and APIs, then verifies each finding before reporting it. That tells you if the weakness is a real, exploitable risk in your environment or a false positive you can safely deprioritize.
